| 초록 | Polymeric membranes still have low permeability and selectivity compared to ceramic membrane and other process such as absorption and adsorption methods. Many researchers have studied to complement this weakness. Improved permeability of membranes can be achieved by controlling diffusivity and solubility. Poly(ethylene glycol)(PEG), rubbery polymer, can improve solubility. Molecular weight and mole percent of PEG were controlled to investigate the effect of PEG. Chemical structure and component of nanofiber were determined by fourier transform infrared (FTIR) spectroscopy and differential scanning calorimetry (DSC). Single gas permeation properties were evaluated for oxygen, nitrogen, carbon dioxide. These properties were measured by constant volume and variable pressure method. The gas permeability was calculated when the permeation reaches a steady state. The gas permselectivity was calculated from the permeability ratio of two gas species. |
